Electrical Connection
Connect power cord to power supply designated on pump label. Do not
use long extension cords as they cause substantial voltage drop, poor
pump performance and may cause motor overload.
HS12-30HT1, HS12-40HT1 and HS18-30HT1 models are 115 volt 60Hz models, fitted with NEMA 5-15P
plugs intended for direct connection to a three pin wall socket.
HS18-40HT2 models are 230 volt 60Hz only and are fitted with NEMA 6-15P plugs intended for direct
connection to a 6-15R three pin wall socket. The color codes are: Green = Ground/Earth, Black = Hot,
Active or L1, White = Neutral or L2.
Power connections and wiring must be carried out by an
authorized electrician.
All wiring must conform to National (NEC), CSA, state, provincial, and local codes. Power supply
voltage, phase and controls must match motor.
Never run a normal pump dry. The Hydrascan ® CL will detect when your pump loses prime (no
water available to pump). When it does this it will display the red warning (led) light and shut
down the pump. Should this happen consult the troubleshooting guide.
The Davey Hydrascan ® CL fitted to this pump has a low pressure indicator light mounted
on its side panel, adjacent to the yellow button. This light will be illuminated whenever the
Hydrascan ® CL senses low pressure. The light will only work when unit is connected to the
correct electrical supply.
Adjustable cut-in screw setting
®
The Hydrascan
CL on your pressure booster system has a preset cut-in pressure, as per the table below.
For most applications this will be satisfactory. In some cases a different cut-in pressure may be required.
This can be achieved by following the instructions below.
These are some of the circumstances where adjustment to the cut-in may be required:
•
High static (vertical) heads e.g. where the pump is more than 50 feet below the highest outlet.
•
When pumping from shallow wells or cisterns (holding tanks).
•
Large existing pressure tank used as well or instead of Davey Supercell 8C. In this case it may
take some time for the system pressure to drop low enough for the pump to start. This may cause
inconvenience setting shower temperatures. By increasing the cut in pressure, you can reduce the
delay before the pump starts, allowing you to set shower temperatures quicker.
•
HS12-30HT1 or HS18-30HT1 used where a lower cut-in pressure may provide a larger tank draw-off
capacity. These models may be set to cut-in at 30psi if desired. Tank pre-charge would need to be
adjusted to 28psi in such circumstances.
